Fitment Notes
- Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
- Chassis code is omitted for rows where the supplied fitment feed truncated the chassis field; verify by VIN or engine code for those applications.
Installation / Use / Maintenance Tips
- Replace shock absorbers in pairs on the same axle to maintain balanced damping and even handling.
- Do not remove the packaging strap or compress the new shock until it is positioned for installation.
- Prime a gas shock by slowly extending and compressing it by hand several times in the vertical position before fitment.
- Inspect upper mounts, bump stops, dust boots, and related bushes during installation and replace any worn items.
- Tighten mounting fasteners with the suspension loaded at normal ride height where the vehicle service procedure requires it.

Great product
Flavor Name: Unflavored, Size: 4 Fl Oz (Pack of 1)
Product is easy to use. Started out slow as it recommends. It never caused upset stomach. I use it daily in my first water of the day. There is no flavor to it nor smell. I recommend this product.

Add the right amount
Flavor Name: Unflavored, Size: 8 Ounce (Pack of 1)
Previous reviewers are adding too much of Concentrace to filtered water. Add only about 20 drops in a gallon of Zero Water filtered water.
This will bring the TDS (total dissolved solid) from 0, after using the Zero Water pitcher, which is basically distilled water, to about 110 TDS an ideal level.
This doesn't mean that this will replace all of your daily mineral needs because water alone is not designed to do this. You will get the rest of the needed minerals from food and any supplements that you may take.
You may also want to consider using a LifeStraw pitcher after filtering with the Zero Water pitcher. Because the Zero Water will remove all dissolved solid including some bacteria, PFAS, and microplastics. But LifeStraw will remove most of the microplastics, DBPs, VOCs, PFAS and pharmaceuticals.
One long filter in the Life Straw pitcher will last over a year since you're already using filtered water, but the round filter would need more frequent replacement - it has 2 parts. You must use both filters in the Life Straw pitcher, even after using the Zero Water pitcher.
There's a new documentary special on Netflix (May/'26) on microplastics and its dangers that everyone should see. Extremely informative.

I'd give them 20 stars if I could
Flavor Name: Unflavored, Size: 8 Ounce (Pack of 1)
I'd give it 20 stars if I could.
I thought I was really healthy. I work out, eat organic, drink RO water, take vitamins/glandulars and this last month something was really wrong.
I was having panic attacks so frequently and strongly I began finding reasons to not leave the house.
I was wondering if I were starting to have a deeper health issue and I began taking these not really thinking they'd do very much.
BOY WAS I WRONG.
I legit feel like I have my life back.
Anxiety gone.
Panic attacks disappeared.
Deeper quality of sleep (still working on length).
My eye sight feels sharper.
I feel happier.
I'm back to the "old me" that I didn't really know was gone in the first place.
Nothing else has changed in my life. It's THIS. I've told my closest friends and boyfriend about this because apparently my body is stripped of minerals and it was trying to get my attention.
I can't rave about this product enough.

A Game-Changer for Daily Vitality
Flavor Name: Unflavored, Size: 2 Fl Oz (Pack of 1)
Switching to a liquid formula has completely transformed my morning routine. I noticed a significant boost in my energy levels almost immediately, likely because the absorption feels so much more efficient than traditional pills. The taste is surprisingly pleasant, making it easy to stay consistent, and I love the peace of mind that comes with getting a comprehensive blend of essential nutrients in one simple dose. It is a fantastic option for anyone looking to support their overall wellness without the hassle of swallowing oversized capsules.
